SPENCER ATTORNEY United StatesPatent Office2,889,081 Patented June 2, 1959 DISPENSING-CAP FOR CONTAINERS "ClarenceSydney Spencer, Creighton Mine, Ontario, Canada Application July 26,1957, Serial No. 674,521

3 Claims. (Cl. 222-153) This invention relates generally to an improveddispensing-cap for containers of the character utilized for dispensingtooth powder or the like.

A primary object of invention is to provide a dispensing-cap for acontainer of the character set forth, the dispensing-cap including meansfor readily dispensing material contained within the container and meansfor preventing dispensing of the material.

Another object of the invention is to provide a dispensing-cap forcontainers which includes a cylindrical cap telescopically received onthe tubular neck portion of a container, said neck and cap includingcooperating means permitting material to be dispensed from the containerand preventing dispensing of the material, the cap and neck of thecontainer including cooperating lock means therebetween facilitating theassembly of the cap on the neck of the container preventing relativelongitudinal movement therebetween.

Other objects and advantages of the invention will become appararentduring the course of the following description. In the drawing there isshown one preferred embodiment of the invention. In this showing:

Figure 1 is a perspective view of a fragmentary portion of a containershowing a dispensing-cap mounted thereon, the parts being shown in aclosed condition;

Figure 2 is a perspective view similar to Figure 1, showing the parts inan open condition;

Figure 3 is a transverse section taken on line 3-3 of Figure 1;

Figure 4 is an enlarged vertical section taken on line 4--4 of Figure 1;

Figure 5 is a fragmentary perspective view of the neck portion of thecontainer upon which the dispensing-cap is mounted;

Figure 6 is a perspective view of the dispensing-cap; and

Figure 7 is a perspective view of a lock ring utilized for mounting thedispensing-cap on the neck portion of the container.

Referring to the drawing, a fragmentary portion of a containerconstructed of any suitable material is indicated generally at 10, thecontainer having mounted thereon a dispensing-cap indicated generally at12 which is retained thereon by means of a lock ring indicated generallyat 14.

The container 10, see Figure 5, includes a body portion 16, afragmentary portion thereof being shown, terminating in a tubular neck18 having a circular cross section. The neck 18 has extending about anintermediate portion thereof an annular groove 20. Extendinglongitudinally from the upper end 22 of the neck and from one sidethereof is an arcuate gate or shield 24, the outer surface of whichbeing in co-planar relationship with the outer surface of the neck 18.The neck 18 com- 2 municates with the interior of the container 16. iThe plate 24 has formed therein a blind bore portion 26 for receiving asuitably conformed abutment pin 28 which will extend laterally from theshield 24 when the dispensing-cap is assembled on the container neck.

The cap 12 includes a cylindrical body 30, closed at its top asindicated at 32 and a countersunk transverse aperture 34 which willoverlie the outer surface of the shield 24 when the dispensing-cap isclosed as seen in Figure 1. Extending transversely of the aperture 34 isa groove 36 which will be in alignment with the abutment pin 28 fororienting the cap in its closed position, and engaging the diametricalopposed side edge portion when the cap is open as seen in Figure 2. Thebody 30 incorporates about the inner periphery thereof an annular groove38 alignable with the groove 20 of the neck 18, the groove 38, seeFigure 4, having a V-shaped cross section forming a shoulder 40 normalto the longitudinal axis of the cap.

The lock ring 14 includes a circular body or ring 42 split transverselyas indicated at 44 to facilitate the disposition of the body in theannular groove 20 of the neck. Formed in circumferentially spacedrelationship about the body 42 are a plurality of resilient laterallyextending teeth 46.

The body 30 incorporates a lower inwardly beveled edge 48 facilitatingthe assembly of the dispensing-cap on the neck 18.

Considering Figures 5 and 7, the lock ring 14 is first disposed in theannular groove 20 of the neck 18 of the container. Next the cap 12 istelescoped onto the neck 18, the edge 48 of said cap engaging the teeth46 of the lock ring and disposing the same inwardly until said lockteeth engage the shoulder 40 of the groove 38. The lock ring 14 willpermit relative rotation of the cap with respect to the neck, but willprevent longitudinal displacement of the cap relative to the neck, thelock teeth 46 being urged into greater locking engagement in the groove38 when such longitudinal displacement is attempted. After the cap hasbeen disposed on the neck, the abutment pin 28 is inserted in the bore26, being retained therein by means of a suitable adhesive.

It is to be understood that the form of the invention shown anddescribed is to be taken as the preferred example of the same and thatvarious changes in the size, shape and arrangement of the parts may bemade as do not depart from the spirit of the invention or the scope ofthe appended claims.

I claim:

1. In combination, a container including a tubular neck having acircular cross section, an arcuate shield extending longitudinally froma fragmentary circumferential portion of one side of said neck, acylindrical cap rotatably received on said neck and including atransverse aperture alignable with said shield for preventing thecontents of the container from being dispensed, and lock means engagedbetween said cap and neck permitting relative rotation therebetween andpreventing removal of said cap from said neck, said shield includinglateral abutment means projecting into said aperture limiting relativerotation between said cap on said neck.

2. In the combination as set forth in claim 1 in which said lock meansincludes aligned annular grooves on respective adjacent outer and innersurfaces of said neck and cap, and a lock ring in one of said grooves,said lock ring including circumferentially spaced, laterally extendingand displaceable lock teeth extending into said other groove.

3. In the combination as set forth in claim 2 in which said onegroove'is formed'in the outer periphery of said neck, the other grooveis formed on the inner periphery of said cap and includes an inwardlyextending shoulder portion engageable with said circumferentiallyspaced, latera lly extending and displaceable lock teeth for engagingthe terminal ends thereof during attempted longitudinal displacement ofsaid cap relative to said neck.
